I replaced GRUB 2.00 with 2.02 in my build automation which creates an installer ISO. Installation onto the VM is also largely automated. GRUB 2.02 (and 2.00) work fine if I revert the config file to that in 1.42.13. > > To be clear: I don’t believe any of the code changes between 1.42.13 and 1.43.4 cause this issue. The problem arises from just the changes in the built-in default configuration file that gets installed. A distro that uses its own custom configuration file may not encounter this issue. > > >> Grub should be fine, however syslinux still suffers issues with 64-bit >> feature.

I don’t recall whether I tried booting directly into GRUB so I will test that tomorrow. > Sysllinux chain-loading is not a factor (GRUB 2.00 still fails to boot w/o it). GRUB 2.02 does resolve the issue. The command line for 2.02 required a “-p” switch which 2.00 does not. This probably caused an uncaught and unnoticed failure during installation in my previous testing. Regards, Felipe
